The HOBO Occupancy/Light data logger monitors room occupancy up to 5 or 12 meters away (depending on the model) as well as indoor light changes with its integrated sensors. Using HOBOware®, you can easily configure both channels to record occupancy and light on and off conditions for building energy audits. This compact data logger has a built-in LCD screen for checking status, remaining battery level, and memory consumption. You can also use the LCD screen to quickly calibrate the logger to the light level in the room or select preset sensitivity thresholds with HOBOware. There are two models of both types of loggers: the UX90-005/-006 has a memory capacity of 128 KB while the UX90-005M/-006M has 512 KB.
